Engine peeing

[Wall-or-Bass]

I recently purchased a used boat with a 2002 200 Optimax on it. I noticed that the engine does not always spit a constant stream of water, especially at idle speed. Looked at the water temp, though, through the Smart Gauges, and the temp does not vary much (only 3 - 5 F). I called the salesman and he said that the water pump is thermostatically controlled, so it may not always spit water constantly. I thought this made sense, but I sure would like to verify this before I have a problem. Can anyone else provide any insight?

Thanks,

Keep your eye on those smart gauges. I wish I had them. I do have a water PSI gauge that I watch on my 200 Opti. Mine has a weak stream at idle but get her flying and my PSI gauge is up near 20. You should be fine

Wall,

I bought a 96 175 EFI this year and when I went to pick it up, I told the guy I wanted to see it run. He put the muff's on and fired it up, nothing out of the indicator hole, so we shut it off. He called his uncle and asked him what to do, the uncle said it's thermostatically controlled, just let it run and warm up. So we started it up and let it run, it took about 2-3 minutes before it came out the indicator hole, we were both getting a little nerveous!!! One thing to remember, most of the cooling water comes out through the exhaust, the indicator is just a visual way of ensuring the water is going through the system.

Thanks for the replies, Guys.

I finally got an engine overtemp alarm this past Friday. Called the dealer and they said to bring it in. The service guy said that the water pump is thermostatically controlled, but that it should always spit water because of a bypass.

To make a long story short, they ended up replacing the impeller, and now the engine is always peeing. Sure makes me feel better.

thats a great thing to know that they should allways be peeing
